Pull-out shower head for kitchen

Abstract

A pull-out spray head, which is connectable with a faucet by a flexible hose, has a water conveyance body disposed within an outer enclosure. The water conveyance body has a cavity which is arranged substantially transversely to the water delivery direction, has an opening facing toward the water intake duct defined by the body, and is divided into two facing portions on opposite sides with respect to the opening. Each facing portion has a water delivery port connected, respectively, to the peripheral ports and to the central port of a disk which locks the body within the enclosure. One of the facing portions is provided with a hollow plug or slider which includes a port for connection to the water delivery port of that one facing portion. A flow control element is positioned within the body and has a rod which protrudes outwardly of the enclosure so as to be connected to an actuation lever.
